Fast shutdown of large scale-up processes

A method comprising:

• tracking, by at least one processor during a startup of a process, code locations of the process in a memory;
• tracking, by the at least one processor during runtime of the process and in response to the tracking the code locations, memory segments allocated to the process;
• receiving, by the at least one processor, an indication for a shutdown of a process;
• waking, by the at least one processor and in response to the indication, at least one processing thread of a plurality of processing threads allocated to a database system;
• allocating, by the at least one processor, a list of memory mappings to the plurality of processing threads, the list of memory mappings comprising a subset of the memory segments allocated to the process, the subset assigned to a first processing thread of the plurality of processing threads;
• freeing, by the first processing thread, the physical memory assigned to the processing thread by the memory mappings;
• and
• returning, by the at least one processor and after all processing threads finish freeing the physical memory assigned to the processing threads, control for shutting down the process to an operating system of the at least one data processor.

A non-transitory computer readable medium storing instructions which, when executed by at least one processor, cause operations comprising:

• tracking, during startup of a process, code locations of a process in the at least one memory;
• tracking, during runtime of the process and in response to the tracking the code locations, memory segments of the at least one memory allocated to the process;
• receiving an indication for a shutdown of a process;
• waking, in response to the indication, at least one processing thread of a plurality of processing threads allocated to a database system;
• allocating a list of memory mappings to the plurality of processing threads, the list of memory mappings comprising a subset of the memory segments allocated to the process, the subset assigned to a first processing thread of the plurality of processing threads;
• freeing, by the first processing thread, the physical memory assigned to the processing thread by the memory mappings;
• and
• returning, after all processing threads finish freeing the physical memory assigned to the processing threads, control for shutting down the process to an operating system of the at least one data processor.
